Research on Model of Micro-grid Green Power Transaction Based on Blockchain Technology and Double Auction Mechanism

The conflict between climate change and energy scarcity has recently gained widespread attention. The development and promotion of green power and renewable energy is an efficient strategy to address this issue. The widespread use of distributed renewable energy in microgrids results in decentralized power supply. The features of distributed power trading, such as low single transaction volume and frequent transaction intervals, present both possibilities and problems to the green electricity market. The usual centralized control and selling of power are no longer appropriate in this circumstance. This study proposes a decentralized energy transaction system architecture in the microgrid and connects the double auction mechanism to achieve the interests of each participant based on blockchain technology and the status quo green power trade in China. Finally, using the trading strategy and model, this study constructs a real and operational energy trading platform, and simulated experiments demonstrate the dependability and efficacy of the proposed trading mechanism.
